Subject: [PATCH 00/11] x86: misc prep patches for virtually mapped stacks

Hi Ingo-

Here are eleven miscellaneous, mostly standalone x86 patches that I pulled
from the virtually mapped stack patch set.  They're based on 4.7-rc6, and
I imagine they apply cleanly on most or all -tip branches.

Once these land, I'll see if the THREAD_INFO_IN_TASK stuff splits out
cleanly as well.  That code certainly needs a couple of these patches,
but I think it might get stuck behind "signal: Consolidate
{TS,TLF}_RESTORE_SIGMASK code", and I asked akpm to queue that one for
-mm.

Andy Lutomirski (10):
  x86/cpa: In populate_pgd, don't set the pgd entry until it's populated
  x86/mm: Remove kernel_unmap_pages_in_pgd() and
    efi_cleanup_page_tables()
  x86/dumpstack: Try harder to get a call trace on stack overflow
  x86/dumpstack/64: Handle faults when printing the "Stack:" part of an
    OOPS
  x86/mm/64: In vmalloc_fault(), use CR3 instead of current->active_mm
  x86/dumpstack: When OOPSing, rewind the stack before do_exit()
  x86: Move uaccess_err and sig_on_uaccess_err to thread_struct
  x86: Move addr_limit to thread_struct
  x86/smp: Remove stack_smp_processor_id()
  x86/smp: Remove unnecessary initialization of thread_info::cpu

Ingo Molnar (1):
  x86/mm/hotplug: Don't remove PGD entries in remove_pagetable()
